How It Is Done continued...
You will lie on your back on
an X-ray table. Ask for a pad or blanket to make yourself comfortable. A strap,
tape, or sandbags may be used to hold your body still. A lead apron may be
placed under your genital and pelvic areas to protect them from X-ray
A round cylinder or rectangular box that takes the
pictures during fluoroscopy will be moved above you. The fluoroscope will move
under you during the test.
The place where the catheter will be
inserted (in the groin or above the elbow) will be shaved and cleaned. Your
doctor will numb the area with a
local anesthetic. Then he or she will put a needle
into the blood vessel. A guide wire will be put through the needle into the
blood vessel and the needle will be removed. The catheter will be placed over
the guide wire and moved into the blood vessel. The catheter then will be
guided through the blood vessels until the tip is in the area to be studied.
Your doctor will use the fluoroscope to watch the movement of the catheter in
the blood vessels.
When the catheter is in place, the dye is
injected through it. You may be asked to take a breath and hold it for several
seconds. Several X-ray pictures will be taken one after another. These will be
available right away for your doctor to look at. You need to lie very still so
the pictures are clear. More pictures may be taken. See a picture of
how an angiogram is done .
An angiogram takes 1 to 3 hours. The
catheter is taken out after the angiogram, and pressure is put on the needle
site for 10 to 15 minutes to stop any bleeding. A small sandbag or clamp may be
put on the site to hold pressure. A bandage is put on the site. You will be
given pain medicine if you need it.
If the catheter was put in a
vessel in your arm, you should not have any blood taken from that arm or your
blood pressure measured in that arm for several days. You will rest in bed
after the test for several hours. If the catheter was placed in the groin area,
try to keep that leg straight for 8 hours. Your doctor will give you specific
instructions after the test. You can use an ice pack on the needle site to
relieve pain and swelling.
The place in your hands and feet where
your heartbeat (peripheral pulse) can be felt may be marked with a pen. Your
pulse may be checked before and after the angiogram.
How It Feels
You may feel a brief sting or pinch from
the numbing medicine. Most people do not have pain when the catheter is in the
